IMPROVEMENT IN RIVVOLVING SPADE-PLOUGE tite Schmitt nfemr tu in ttmtetten @mit ma mating part nf tti time,

TO ALL WHOM IT MAY C()l\l'(`}1lRl\l':V

Be it known that I, JAMES W. MILRGY, of Galveston, in the county ofCass', and State of Indiana,`ha'v`e inventedcertain new and lusefulImprovements in'Revolving Plough and Cultivator; and Ido `hereby declarethat thefollowing is a. full, cleans-.nd exact description thereof,reference being had to the Aaccompanying drawings,- and to the lettersof reference marked thereon, which form a part of this specification, inwhich-:- Figure 1 represents a side elevation of my machine. i Thenature of this invention consists inarranging'two series of spadeqvheelsin the'uianner hereinafter' set forth. i

To enable others skilled in the art to makeand use my invention', I willnow describe its construction and operation.

- The frame of my machine consists in the sidepieces A and-uprights B B,which are strengthened by braces c c. The frame is designed to rest onthe axles of a common wagon, the front end ofA said frame acting as abolster, to enable the fore-wheels of the wagon to turn to the right orleft. A

Inside of the above-mentioned frame is hinged, at its front end, asecond frame, D, having on it the uprights n n, strengthened bythebraces en m.

i k'represents an axle, which is pivoted in the opposite `sides of frameD. On the said axle are adjusted three'wheels R R, supportedv byarmss s.To the periphery of wheels'- R R are fastened, in any suitable way, thespades t, which are intended for'dividing and pulverizing the clods, 'soas to render the: ground in u. proper condition for receiving the seed;v i i i Near the upperends of uprights n n is the axle G, having on itlthe same number of spade-wheels R' as is formed on axle 7:. i A

It will beobserved that the-wheels on axle G are made sluuller thanthose onv axle le, and are furnished with spades similar in form tothose of le 7c. i It will also-be seen that the spades `on the upper andlower 4wheels -ere made .to interlock, so that, when motion is given to'the lower wheels, by the'spades coming in contact with the earth, theseme motion will beimparted t the-upper wheels. The object of the upperVwheels is to crush or pulverize any earth that may adhere to the surfaceof. the spadeson the lower wheels.

-To the rear end of fram'e D the eordsv v are attached, the upper endsof said cords being fastenedfto roller H. In operating said roller bythe crank at its-end, the'cords will place the frame D at the'desiredangle, and the spades on the lower wheels made to penetrate the soil tothe desired depth.

may he found advantageous, at times, to sub'stitute forks, with three orfour tines, inplace ofthe spades above described. l

Zdesignates a pawl, pivoted to the inner side of one of the braces c'cof the frameA. Said pawlis designed to it into the serrated part of theroller H, order to preventit from revolving when'pecessary'.

What I claim as new, and desire to secure by Letters Patent, is

1. In a revolving spade-plough, the hinged frame D, operatingsubstantially as and for the purpose set forth. i t

2. The employment 'of` one or more'revolving ploughs orvforksLarrangedto operate substantially as described. i 3. I claim the combination ofthe lower spade or forked wheelsR R, with the upper wheels R B. gearingtherein,l substantially in the manner and for the purpose set forth. Y p

' clhim the combination of the frame A, roller` H, pawl l, and cords vv,`all arranged and operating ,substantially as and for the purposespeci-fied.

In testimony that I claim the foregoing as my own, Iaiiix my signature'in presenceofl two witnesses.-
